Title: Determining Percent of Seed GerminationEnhancing mathematics in the career/technical classroom and providing relevance in the mathematics classroom
Description:
In this project, students will conduct an experiment to determine the percentage of seed that will germinate in a given time frame. Students will produce charts and graphs to represent the results algebraically. Mathematics and career/technical students can participate in this lab experiment together, or the activity can be conducted separately in either classroom. The mathematics teacher will want to adapt the student handouts to provide additional emphasis on mathematics and to remove emphasis on the career/technical.
This integrated lesson is the result of collaboration between Chip Blanton, an agriculture teacher, and Greg Pendergrass, a math teacher (Fort Payne HS). For information about using the eight step model for developing integrated projects developed by the Southern Regional Education Board, contact Leslie Carson at leslie.carson@sreb.org. For information about the project implementation, contact Chip Blanton (cblanton@ftpayk12.org) or Greg Pendergrass (gpendergrass@ftpayk12.org).
Standard(s): [MA2013] AL1 (912) 46: Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data. [SID7]

Title: Linear Alignment
Description:
In this Illuminations lesson, students explore linear equations and the effects of changing the slope and yintercept on a line. It gives students exposure to y = mx + b, and can be used as an introduction to the topic. Using graphing calculators, students are challenged to overlap lines onto the sides of polygons. To achieve this goal, students change slopes and yintercepts of lines, noting observations about behavior as they work. As students change the yintercept of a line, they see it raise or lower the line. As students change the slope, they see it affect the steepness of the line.

Description: In this lesson, one of a multipart unit from Illuminations, students interpret the meaning of the slope and yintercept of a graph of reallife data. By examining the graphical representation of the data, students relate the slope and yintercept of the least squares regression line to the reallife data. They also interpret the correlation coefficient of the resulting least squares regression line. This lesson incorporates an interactive regression line applet.

Title: Movement with Functions
Description:
In this unit of 3 lessons from Illuminations, students use movement to reinforce the concepts of linear functions and systems of equations. Multiple representations are used throughout, along with tools such as motion detectors and remotecontrolled cars. Students explore how position, speed, and varying motion are reflected in graphs, tables, and algebraic equations.
Standard(s): [MA2013] AL1 (912) 46: Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data. [SID7]

Title: How Did I Move?
Description:
In this Illuminations lesson, students are provided with a method for understanding that for y = mx + b, m is a rate of change and b is the value when x = 0. This kinesthetic activity allows students to form a physical interpretation of slope and yintercept by running across a football field. Students will be able to verbalize the meaning of the equation to reinforce understanding and discover that slope (or rate of movement) is the same for all sets of points given a set of data with a linear relationship.

Title: Investigating Pick's Theorem
Description:
In this unit of three lessons, from Illuminations, students rediscover Pick's Theorem, which they were likely introduced to in middle school, and use algebra to determine the coefficients of the equation. They explore the concept of change as a mechanism for finding the coefficients of Pick's Theorem.

Title: Rates of Change in Pick's Theorem
Description:
In this lesson, one of a multipart unit from Illuminations, students use a spreadsheet to investigate rates of change among various figures created on a geoboard. The coefficients of Pick s Theorem are easily determined from these rates of change.
Standard(s): [MA2013] PRE (912) 17: Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. Estimate the rate of change from a graph.* [FIF6]

Title: Growth Rate (Slope)
Description:
Given growth charts for the heights of girls and boys, students will use slope to approximate rates of change in the height of boys and girls at different ages. Students will use these approximations to plot graphs of the rate of change of height vs. age for boys and girls.
Standard(s): [MA2013] AL1 (912) 46: Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data. [SID7]

Title: Using Graphs, Equations, and Tables to Investigate the Elimination of Medicine from the Body: Modeling the Situation
Description:
This threepart eexample from Illuminations illustrates the use of iteration, recursion, and algebra to model and analyze the changing amount of medicine in an athlete's body. This example includes: (1) an interactive environment used to become familiar with the parameters involved and the range of results that can be obtained, (2) an interactive environment used to investigate how changing parameter values affects the stabilization level of medicine in the body, and (3) an interactive graphical analysis that provides a visual interpretation of the results. eMath Investigations are selected eexamples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The eexamples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the eexamples are natural companions to the iMath investigations.
